SHAFT- BEARING.

SPEGIFICATION forming part of Letters To (1.71 1H1 0m it may concern.-

Be it known that I, ADoLPH HAENICHEN, a citizen of the United States,residing at corner Prospect street, in the city of of Broadway andPaterson, county of Passaic, and State of New Jersey, have inventedcertain new and useful Improvements in Shaft-Bearings; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make andnse the same, reference being had to theaccompanying drawings, on, which form a part of this specification.

.This invention relates to mountings for revoluble shafting, and it hasreference particularly to mountings and described in my copendingapplication for Jnited States Letters Patent, filed February 29, 1900,Serial No.3,083.

One object of the invention is to so mount a shaft of the nature aboveindicated that the production of friction will be reduced to the minimumand the hearing be as simple and durable as possible.

A further object of the invention is to no construct and arrange thebearings for a vertical shaft such as that shown-and described in mycopendingapplication forUnited States Letters Patent for aspinning-machine, filed January 29, 1900, Serial No. 3,083, that theshaft may with facility be removed when occasion requires.

A still further object of the invention is to.

so construct a bearing designedto counteract the tendency of a'shafttoward longitudinal movement that the parts thereof may beselfnotwithst'anding uneven wear or the fact that the shaft is notdisposed perfectly perpendicular with'reference tosaid bearing.- V

The invention consists in the improved mountings for revoluble shaftingand in the combination and arrangement of the various parts-thereof,substantially as will be hereinafter pointed out and finally embodied inthe clauses ofthe claim.

Referring to the accompanying drawings, Figure 1 is a view in sideelevation of the end portion of a spinning-machine, showing Applicationfiled March 21, 1900. Serial No. 9,497.

and to letters of reference marked therefor the'shafts of aspincling-machine substantially like that shown Patent No. 664,946, datedJanuary 1, 1901.

(No model.)

certain revoluble shafts and-the mountings therefor. Fig. 2 is anenlarged view, in side elevation, of a vertical shaft and its mountings,the latter being shown partly in section. Fig. 3 is a view in frontelevation of the upper mounting for said vertical shaft; and Fig. 4 is aview of a portion of a horizontal shaft and one of its mountings, thelatter being partly shown in section.

In the accompanying d rawings,(.l. designates the frame of aspinning-machine, while I) dening-machine and adapted to deliver threadontobobbins which may be arranged in brackets c and are adapted tobedriven by rollers (I, mounted on horizontal shafts e, which arejonrnaled in the frame. f denotes a vertical 11mm ublc shaft carryingsheaves g, over which extend he s-.12.. that bear against the whirls iof said spindles, so as to rotate thelatter. j design-ates a system ofgearing operatively connecting each shaft 6 with a worm is on saidvertical shaft.

'l and m are the pedestals for supporting the vertical shaft f. Each ofthese pedestals consists of a plate n, having a pair of alined ver- 1tical slots 0, adapted to receive the bolts for securing the pedestalsto the end upright of the frame a. Since the slots extend vertically ineach plate, the pedestal is rendered vertically adjustable when thebolts are loosened. 'lhe pedestal l, which constitutes the step-bearingfor said shaft, has a socket 1'), adapted to receive the lower end ofthe shaft f, and in the top surface of said pedes tal is formed aroundthe socket an annular channel q, inwhich are arranged antifriction-balls1-. Upon the shaft f is secured a collar 5, said collar being rigidlysecured in position by means of a feather-and-key arrangement t. Betweensaid collar and the pedestal and washer u. lhis washer is of glass-hardsteel. By virtue of this provision a bearing of the maximum durabilityis produced.

The'pedestal of constituting the bracket and having the slots 0 abovedescribed and the other part w being the upper socket or pedestal properfor the shaft. The two parts have pairs of projections m, which arepenetrated by bolts y notes spindles rcvolubly mounted in said spin m isdivided, one part 1; there for securing said parts together. The part tois provided with a socket z, the same as thesocket p of the lowerpedestal, with the exception that it is somewhat larger. In this socketis arranged a cup-bushingor thimble 1, directly receiving the end of theshaft. This thimble is adaptedto be properly set by a screw 2, mountedin the top of the pedestal andadapted to bear against the top of thethimble. V

By arranging the pedestals so as to be vertically adjustable the shaft fmay be removed without -entirely removing either pedestal from the frameand without appreciable longitudinal movement of the shaft. The sheavesdo not have to be loosened, as they would have to be if the shaft wereremoved longitudinally, for the reason that they project into more orless confined openings in the upthe shaft Into each pedestal orplumber-block 4 for the shaft 3 is screwed an annular bushing 9, whichis penetrated by the shaft 3, the adjacent interior edges of saidbushing and the plumber-block being chamfered 'olf to form a ball-race.10, in which are arranged about the shaft antifriction balls 11. Uponthe shaft and between and close to the plumberblocks are secured collars12. These collars are fixed adjustably by means of binding screws 13.The face 'of each pedestal or plumber-block adjacent the adjoiningcollar is provided with an an'nularball-race 14, in which is arrangedanother set of autifrictionballs 15. Against each set of these balls isadapted to bear a glass-hard steel washer 16, corresponding to thewasher u, said washer being interposed between the pedestal and thecollar and acting, when the collar is properly secured in place, to keepthe balls in their groove. Each 'glasshard washer 16 serves the samefunction as does the corresponding washer u for the vertical shaft.-- v

The reason for providing the collars 12 and the bearings disposedbetween them and the plumber-blocks grows out of the fact that theworm-and-worm-wheel connection between the shaftsfand 3 tends to imparta longitudinal thrust to saidshaft 3, as indicated by.

the arrow in Fig. 4 Ofcourse it depends upon the direction-"in which themachine is working as to whether the shaft f will tend to be moved inthe one or the other direction longitudinally.

dicated by the reference character 17 in the figure mentioned, havingits fiat surface resting upon the balls 7', while the curved portion ofits surface sits in a correspondinglyshaped recess 18, formed in thecollar 8. The edges of the opening 19 in this washer may be rounded off,so that the shaft cannot possibly interfere with the action of saidwasher.

It will be observed that by virtue of this construction whatever theposition with referalways self-adjusting, so as to work perfectly true.i

Since I usually secure the upper pedestal to a cross-bar 20 of theupright, which has strengthening-flanges 21, between which the part '0of said pedestal is bolted, it is in order that the shaft f may bereadily removed notwithstanding the fact that the up'per one of theseflanges and the worm 8 coact to prevent dismounting the shaft that Idivide the upper pedestal. Said pedestal being made in two parts, uponremoving the bolts securing them the shaft f may be lifted till the Wormand worm-wheel clear each other, and then it canbe removed withoutinterfering with any other parts.

Having thus fullydescribed my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a frame, of a vertical shaft, pedestalsdisposed the one above the other, said lower pedestal being adjust ablysecured to the frame and receiving the lower end of said shaft, a collarfixed on said shaft, a'hardened washer penetrated by said shaft, aball-race in the lower pedestal and surrounding the shaft, ballsarranged in said ball-race, said washer being interposed between thecollar and the balls, and said upper pedestal comprising a socketportion and a bracket portion having projections, and bolts penetratingsaid projections to secure said socket and bracket portions toge her,saidsocket portion receiving the upper end of said shaft and saidbracket portion being adjustably secured to the frame, snbstaa tially asdescribed.
